Natural Resource Partners LP
nrplp.comNatural Resource Partners LP (NRP) is a natural resources company that owns and manages mineral rights, with its soda ash segment operating through Sisecam Wyoming, a trona mining and processing operation in the Green River Basin of Wyoming. Revenue is generated through the sale of soda ash produced from trona ore, with royalty obligations paid to the state of Wyoming, the U.S. Bureau of Land Management, Sweetwater Royalties LLC, and private parties based on production volume and soda ash value (per the 10-K filed 2026-02-27). Sisecam Wyoming mines trona from beds 24 and 25 at depths of 800 to 850 feet, benefiting from shallower deposit access relative to other Green River Basin operators, which enables continuous mining technique and single-shaft hoisting efficiencies. Domestic shipments rely exclusively on Union Pacific Railroad under a contract expiring December 31, 2028, with over 90% of soda ash shipped via that single rail line in FY2025.
